The V century BC Greek architect, son of Eurifronte, who was born in Miletus. He not only built monuments, but that he also directed the construction of entire cities. His first large work was the reform of Piraeus, whose fortifications had begun Themistocles. Also is author of the plane from the city of Rhodes in 408 and Miletus. He also distinguished himself as a politician.
Hippodamus of Miletus has traditionally been regarded as the inventor, or at least the introducer in Greece, plant of cities with streets parallel and straight splitting of an orthogonal network, producing a near-perfect grid, which in his honor called "plant hipodamica". The Roman cities, drawn with a regular design, are a practical application of the general method of the centuriatio, applicable theories of Hippodamus. The constructive ideal of Hippodamus would be reflected in a city embedded in a squared rectangle inside based on straight streets cut at angles of 90 °, lined with columns and space open for places in which urban life will develop.
Despite the fact that as we have already mentioned throughout the 5th century BC in Greece were built some cities according to the planning of Hippodamus, the success of their constructive theories take place later, thanks partly to its spread by Roman planners. Thus, in the modern age, started the colonization of the Americas by European powers and the need to create new cities arise Hippodamus ideas were rescued. In 1502, Nicolás de Ovando drew the plan of the city of Santo Domingo using the plant hipodamica. This type of layout, was taken into account also in the nineteenth-century expansions of some of the great cities of Europe.
In terms of their political theory (which we know through the criticism to which Aristotlesubmitted it), Hippodamus defended the idea that the strength of the institutions of the polis depended on social equality. To reach this goal, among the most favored classes of society and the least not deveria be a great distance since otherwise there would be the imbalance, which would lead in turn to chaos and confrontation between the two groups. To hippodamus, it was necessary to put an end to the oligarchy and tyranny as forms of Government, since both encouraged inequalities. His ideal Government consisted of a situation of collegiality among the aristocracy, royalty and democracy.
